Jack R. Luellen is a principal of Dickie, McCamey & Chilcote, P.C. and the Location Chair of the Denver office. He concentrates his practice in energy law, with a particular emphasis in oil and gas and substantial commercial litigation experience. An effective and strong advocate for oil and gas companies, he represents interests in the E&P and midstream sectors.

Mr. Luellen is involved in the resolution of industry-specific disputes concerning joint venture agreements, operations agreements, breach of contract, surface use and access issues, natural gas processing, construction defects, and payment and recovery of royalties. Clients benefit from his corporate experience, in which he routinely negotiates, drafts and closes agreements for the purchase and sale of oil and gas assets, as well as surface use, processing, marketing, transportation and joint operations agreements. He frequently works with companies and capital providers in connection with debt and equity financings and related corporate governance matters, including corporate structure and formation. Mr. Luellen also counsels his clients on issues surrounding hydraulic fracturing and well-specific activities, such as subsurface trespass, environmental concerns, and insurance disputes.

As an active and influential member of the oil and gas industry, Mr. Luellen provides strategic guidance on regulatory matters and represents clients before state regulatory agencies, including the Colorado Oil and Gas Conservation Committee, the North Dakota Industrial Commission, and the Utah Division of Oil, Gas and Mining. As a leading voice on current issues affecting oil and gas clients, he is a regular presenter at conferences throughout the country and frequently leads discussions on topics such as hydraulic fracturing, water management, operations, transportation, and supply concerns.

Mr. Luellen’s oil and gas practice is informed by his service as Special Assistant Attorney General in the Financial Crimes Division of the Colorado Attorney General’s Office prior to private practice, where his experience includes the successful prosecution and trying of complex securities fraud-related crimes.
